HORSESHOE.

Application filed April 14, 1924. Serial No. 706,223.

To all whom it may concern:

Be it known that I, JOHN FRITZ WALKEN- HORST, a citizen of the United States, residing at Milton, in the county of Trimble and State of Kentucky, have invented cer tain new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates to improvements in horseshoes, and has as its main object to provide a shoe bod with means at the front or toe part by whlch either a flat level surface is aiforded or a calk as desired.

Another purpose is to produce means for interchangeably maintaining a calk or filler in operative position.

A further aim is in the provision of a shoe which can be adjusted for use under ordinary conditions or for icy or otherwise slippery surfaces.

These objects are attained by the novel construction and arrangement of parts hereafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a bottom plan view of a conventional type of horseshoe showing the application of the invention,

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1,

Fig. 3 is a similar but fragmentary sectiOlal view taken on line 33 of Fig. 1, an

Fig. 4 is a like view of the same but showing a filler piece as substituted for the calk.

Referring more in detail to the drawing, the numeral 10 designates in general a common form of horseshoe, the same having the usual recesses 11 near its side edges and holes 12 for the securing means.

Formed in the lower front part of the shoe 10 to extend in a plane at a right angle with its median line, is an undercut or dovetailed recess or groove 13, open at one end at the edge of the shoe and closed at the other.

Fitted tightly to engage in this groove, by driving in from the open end, is a correspondingly shaped element 14 formed on a sharp calk 15; or, if preferred, a calk 15 having a flattened contacting surface may be used, and if no extending calk is desired,

a filler 16 may be employed to occupy the space in the groove.

All these several elements have square cut a entering ends adapted to abut the inner end of the groove, and extending oppositely outward are stems l7 filling the groove to the level of the surface of the shoe and having their outer ends shaped in conformity with the profile of the shoe.

These stems contain recesses 18 in their side edges towards the heel portion of the shoe, these recesses being suited to receive keepers 19 fixed rigidly in the shoe and held in position by a screw 20.

In light summer driving, the filler 16 is preferably used, the same being changed for a calk by removing the screw 20, raising the keeper 19 and driving the filler out, sub stituting for it any preferred calk, which is obviously held by the keeper when replaced.

It will be apparent that should a calk become dulled by use, it can quickly and easily be replaced by a driver, saving time and expense in visiting a farrier, these calk ele ments being quite inexpensive in themselves.

Although the foregoing is descriptive of the preferred embodiment of the invention, it will be clear that minor changes may be made without affecting the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A horseshoe having an undercut groove in its lower surface at the forward end, a straight calk having a part suited to engage in said groove, a notched extension on said calk, and means for removably securing the calk therein by engaging in the notch of said extension.

2. A horseshoe having an undercut groove in its lower surface at the forward end, the groove extending at a right angle relative to the center line of the shoe and being open at one end, a calk having its base portion fitted to engage in the mentioned groove, a stem extending from the calk to the edge of the shoe, said stem having a notch, and means carried by the shoe to engage in the notch and maintain the calk in operative position.

. at one end v a calla having its base portion fitted to engage in the mentioned groove, a

stem extending from the calk to the edge of the shoe, said stein having; a1 recessin its side, a keeper held in a recess in said shoe and having a part engageable in the recess 10 of said stem, and means for reinovably securing said keeper in the shoe.

In Witness whereof I have aflixed my signature.
